An Unusual Location of a Primary Central Nervous System Lymphoma: The Temporal Horn


Figure 1.
Figure 1. Preoperative non-enhanced axial (a), coronal (b) and enhanced axial (c, d) MRI scans demonstrate a large tumor of ovoid shape inside the left temporal horn with homogenous enhancement and peritumoral edema.

Figure 4. (a) The sylvian fissure is split to identify the inferior insular sulcus. The inferior insular sulcus was mapped with dotted white lines. (b) The temporal horn is reached by dissecting the bottom of the inferior circular sulcus of the insula. IL: insula lumen; STG: superior temporal gyrus; MTG: middle temporal gyrus; ITG: inferior temporal gyrus.
